Wilson Combat Flat Mainspring Housing – 1911 Government/Commander

This Wilson Combat flat mainspring housing replaces the factory arched housing on 1911 Government and Commander models, changing the grip angle for shooters who prefer a flatter backstrap profile. The flatter angle can improve natural point of aim and trigger reach for some hand sizes, particularly for competitive shooters and those who prefer a higher grip on the frame.

Machined from steel with a stainless finish for corrosion resistance and durability. Installation requires basic 1911 knowledge—drift out the mainspring housing pin, swap housings, and reinstall. No gunsmithing required, though proper tensioning of the mainspring cap is essential for reliable function. Includes housing only; mainspring, cap, and pin are not included.
